The ProTek R/C 4S 120C Graphene + HV 6500mAh LiPo Battery is a great battery option for anyone looking for a high capacity, high output 4S battery. Weighing 578 grams, the 4S HV is lighter than a standard 4S pack, with much higher capacity. This provides more runtime, and a dramatic increase in voltage and punch over the course of a run.Â
This battery is designed to have improved power to weight ratios while maintaining a low CG. The improved efficiency of this pack will allow for lower operating temperatures and lower internal resistance. This gives users a more consistent battery pack. ProTek Graphene + 120C Packs deliver the power needed by serious racers and enthusiasts alike.
Lab testing has shown that ProTek R/C Silicon Graphene packs have double the cycle life when charged at 1C rates, and can be charged at higher amp rates, with less risk of damage to the pack. More importantly, the discharge curve is flatter, meaning the cells maintain higher voltage throughout the discharge cycle with no significant drop off. Additionally, when compared to conventional LiPo batteries Silicon Graphene batteries are lighter, providing a higher capacity per gram ratio. With 7.6V nominal voltage, 120C discharge ratings, incredibly high charge rates and ten different models to choose from, ProTek R/C 120C Graphene + packs are perfect for racers and bashers that demand the absolute best.
NOTE: This battery is not recommended for high current draw 8S applications.Â

LITHIUM POLYMER SAFETY INFORMATION
IMPORTANT:
1) DO NOT leave the battery in your model when charging
2) DO NOT leave unattended when charging
3) ALWAYS balance charge the battery
4) ALWAYS use a LiPo charging bag
5) YOU MUST use a Li-Poly specific charger to charge the pack (NiMH or NiCD only chargers WILL NOT WORK!)
6) YOU MUST not over discharge the Li-Poly battery pack
7) READ & UNDERSTAND the instructions carefully before operating this battery
NOTE: When using high energy Li-Polymer Batteries, please do not over-discharge or over-charge batteries as this will result in over heated batteries. Discharging capacity can’t exceed 80% of the max capacity of the pack after full charging to ensure a good cycle performance. It is recommended to fully charge a brand new battery before using and only discharge the battery 50% for first 5 cycles. Always monitor race time and/or set a low voltage warning on ESC (End voltage cannot be lower than 3.2v per cell). Do not use the battery that has too low a voltage.
Do not expose batteries to sunshine or store/charge batteries at the temperature above 35°C or in a closed car. The high temperature environment could cause damage to the pack or make it burst. If the battery becomes hot while fast charging, high current discharging or racing, do not charge the battery until it has cooled completely. Wait about 20 mins, then inspect prior to recharging.
